No sound from speakers setting up usb turntable

[Gary Vanderlinden]

I am setting up a usb turntable on my Vista system to record LPs On
the Sound window and the Playback tab shows the speaker Conexant High
Definition Audio as working and default. The gray bars on the left
fluctuate to green when I play something from iTunes and I hear it.
The Sound window and the Playback tab also shows the USB Audio CODEC
speaker working. With the turntable usb cable plugged in and a record
playing the Recording tab on the Sound window shows the USB Audio
CODEC Micorphone as working and default. The gray bars on the left
fluctuate to green with a record playing but no sound comes from the
speakers. None of the speakers on the Sound window and the Playback
tab show any indication they are attempting to playback anything.
